Public Methods

public void addView (View child, int index, ViewGroup.LayoutParams params)

Added in API level 1

Adds a child view with the specified layout parameters.

Note: do not invoke this method from draw(android.graphics.Canvas), onDraw(android.graphics.Canvas), dispatchDraw(android.graphics.Canvas) or any related method.

Parameters
child View: the child view to add
index int: the position at which to add the child or -1 to add last
params ViewGroup.LayoutParams: the layout parameters to set on the child
Throws
IllegalStateException if this switcher already contains two children

public CharSequence getAccessibilityClassName ()

Added in API level 23

Return the class name of this object to be used for accessibility purposes. Subclasses should only override this if they are implementing something that should be seen as a completely new class of view when used by accessibility, unrelated to the class it is deriving from. This is used to fill in AccessibilityNodeInfo.setClassName.

Returns
CharSequence

public View getNextView ()

Added in API level 1

Returns the next view to be displayed.

Returns
View the view that will be displayed after the next views flip.

public void reset ()

Added in API level 1

Reset the ViewSwitcher to hide all of the existing views and to make it think that the first time animation has not yet played.

public void setFactory (ViewSwitcher.ViewFactory factory)

Added in API level 1

Sets the factory used to create the two views between which the ViewSwitcher will flip. Instead of using a factory, you can call addView(android.view.View, int, android.view.ViewGroup.LayoutParams) twice.

Parameters
factory ViewSwitcher.ViewFactory: the view factory used to generate the switcher's content
